EX432 Practice Questions

Check cluster conditions:

oc describe managedcluster cluster-dev

Check agent namespaces and pods on the managed cluster (common namespace names depend on deployment, but you’re looking for ACM/klusterlet agents).

On hub, check managedclusteraddons and addon health:

oc get managedclusteraddon -n cluster-dev

oc describe managedclusteraddon -n cluster-dev < addon-name >

Typical fixes: missing pull secret, network/DNS issues, CSR approval issues, etc. (Exam expects you to identify from events/conditions).

Bind the ClusterSet into the application namespace using ManagedClusterSetBinding.

Create Placement in that namespace selecting the desired clusters.

Deploy application resources tied to that placement (Subscription or GitOps pattern). Why this matters: This is the standard multi-tenant ACM pattern for teams.

On hub: inspect managed cluster conditions for certificate issues.

Check pending CSRs (if applicable in your lab):

oc get csr

Approve relevant CSRs and verify managed cluster returns Ready. Why this matters: Certificate-driven trust is core to “secure clusters” operations in ACM.
